i have a 91 ford bronco and just replaced the fuel pump fuel filter and also the guy I bought it off replaced the throttle position sensor now even after all that getting replaced it still wants to stall out after I let of the gas now I have noticed it isnt so prone to do it if I ease off the gass do you think its a fuel pressure regulator or is the idle set to low or is there another possibility?

If the fuel pressure is bad you can check by pulling the vacuum line running to it. There will be some fuel in the vacuum line. If no fuel is present it is most likely idle air control. Autozone approx. $55.00 to $75.00.

Remove idle air control spray a little carb. Clean on valve and blow dry. Replace. If it seems to cure problem go ahead and replace with new one.
